I think the answer is (x+1)(x-2)(x-3)
The multiples of 14 are 1,2,7,14
the multiples of 22 are 1,2,11,22
Therefore 2 is the GCF
First, you have to establish the fact that there is a correlation because the points are obviously grouped together
The, you have to know that which direction a positive and negative gradient face ( a positive gradient looks like a tick when you join a line to it)
Look at the attachment and the answer is a negative correlation ;)
